Index statistical properties of sparse random graphs
(2015) [Artículo de periódico]Using the replica method, we develop an analytical approach to compute the characteristic function for the probability PN(K,λ) that a large N × N adjacency matrix of sparse random graphs has K eigenvalues below a threshold ... -
Lattice dynamics and spin-phonon coupling in CaMn2O4 : a raman study
(2014) [Artículo de periódico]We present polarized Raman spectra of CaMn2O4 (marokite) measured in several exact scattering configurations from oriented single crystals. Most of the 11Ag + 12B1g + 10B2g + 9B3g Raman-allowed modes are identified and ... -
Semiclassical structure of chaotic resonance eigenfunctions
(2006) [Artículo de periódico]We study the resonance (or Gamow) eigenstates of open chaotic systems in the semiclassical limit, distinguishing between left and right eigenstates of the nonunitary quantum propagator and also between short-lived and ...
